I think you are right ! =
I was trying the following macro to test it :
'macro to turn on or off the statment of use offscreen bitmap,
'from Options/view/enable offscreen bitmap, without having to
'open the options box
'give him a hotmenu icon or a keystroke to be most effective
a=sys(248) 'memorise statment of use offscreen bitmap
if a=1 THEN
sys(248)=0 'don't use offscreen bitmap
else
sys(248)=1 'Use offscreen bitmap
end if
end
it uncheck as well the "enable offscreen bitmap" button, but can not check it ...
I made since a long time ago a similar macro to activate "Select object when created" (very usefull for designing in 3D mode) with a hotmenu icon or a keystroke, to be most effective than having to open successively Option/General and check or uncheck "Select object when created", then "Apply", then close the Option box ... which macro, with simmilar code using sys(242), is running very much, in both directions.
Also, yes, I confirm what Paulerens is saying.
